5-77
This parameter selects the operation of the drive upon a loss of PID feedback signal.
A-10
Sleep Frequency
Unit: 0.1
Settings
d0.0 to d400Hz
Factory Setting: d0.0
A-11
Wakeup Frequency
Unit: 0.1
Settings
d0.0 to d400Hz
Factory Setting: d0.0
A-12
Sleep Period
Unit: 0.1
Settings
d0.0 to d650 seconds
Factory Setting: d0.0
These parameters determine sleep functions of the AC drive. If the command frequency falls
below the sleep frequency, for the specified time in Pr. A-12, then the drive will shut off the
output and wait until the command frequency rises above Pr. A-11. Please see the below
diagram.

Factory Setting: d0.0
When parameter A-13 is set to 0, what F and H display is the actual value of setting
frequency and output frequency. When this parameter is not set to 0, the display value of F
and H = actual value
¯
A-13/1-00. To set frequency with panel, communication, VR, AVI or
ACI need to set according to the display value. For example, when 1-00=60.0Hz, if A-13 is set
to 30.0 Hz, it means when the actual value of frequency is 30.00 Hz, the display value will be
15.0 Hz . If you want to let drive run at 10.0Hz, the frequency command must be 5.0 Hz. But
